2-Methyl-2,3-dihydro-benzofuran-5-carbonyl chloride CAS 55746-01-5

Description

The occurrence of 2-Methyl-2,3-dihydro-benzofuran-5-carbonyl chloride is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Methyl-2,3-dihydro-benzofuran-5-carbonyl chloride (CAS 55746-01-5), a certified reference material (molecular formula C10H9ClO2, MW 196.63 g/mol) for analytical method development and quality control.

The molecular framework of 2-Methyl-2,3-dihydro-benzofuran-5-carbonyl chloride (C10H9ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
